BTW, those using Btrfs can probably use ‘--disable-deduplication’ and be
done with it.

I erroneously used to think that Btrfs could do live deduplication, but
it doesn't.  There are external tools to do out of band / batch
deduplication though [0]; so if they perform better than the guix daemon's
own dedup, perhaps we could document this way out for our Btrfs users.


A little while ago I had hoped to test btrfs with --disable-deduplication and bees [1] as the deduplication agent, but wasn't able to successfully run a system with --disable-deduplication because I needed the deduplication to cover up problem with grafts [2]. Until we resolve the second issue, I don't think we should recommend folks run the daemon with --disable-deduplication.
